I get a kick out of all the military types stroking the prowess of the 308 Win but when the topic of the 30-06 comes up it is considered nothing better then the 308.
Even in its original loads it matches ANYTHING the 308 can produce. Using modern high pressure loadings, it will far out perform the 308.
Anyone that feel the 308 is an acceptable chambering simply can not make the argument that the 30-06 is not at least as capable.
Many will say the 30-06 is not as accurate as the 308. Well, perhaps if your comparing an old 03A in 06 with a modern M40 in 308......
Put them both on an equal platform and I would enjoy seeing someone prove the point that the 30-06 is any less accurate then the 308.
As far as long range shooting. With a properly set up rifle, the 30-06 will easily offer accurate 1000 yard reach with its best ballistic bullets. Personally, for big game hunting, I would limit it to 600-700 yards personally, just as I would the 308 but it will certainly perform at this range on big game.
Its really a matter of the rifle more then the chambering as it is in most cases.
